LG 27GX700A Analysis: Impressive or Deficient? (OLED Tandem Review)
The LG 27GX700A, LG's first fourth-generation OLED gaming monitor, promises a big leap in color and brightness. However, it presents color accuracy issues, disappointing HDR brightness, and a grainy matte coating that affects image clarity. Although it excels in gaming due to its low latency and motion clarity, its shortcomings make it difficult to recommend in its current state.
1. 🚀 First Impressions of the LG 27GX700A: Improved Color, But Not Everything Is Perfect
- ✅ The LG 27GX700A is LG's first monitor with a fourth-generation W-OLED panel (Tandem).
- ✅ It promises greater brightness and better color compared to previous generation panels.
- ✅ Includes two HDMI 2.1 ports and one DisplayPort 1.4.
- ⚠️ Despite the promising specifications, color accuracy presents problems.

2. 🎨 Color Accuracy Analysis: Deficiencies in SDR and Serious Problems in HDR
- ⚠️ In SDR, the monitor shows an excessive red balance and does not correctly follow the gamma curve, affecting details in shadows and whites.
- ❌ In HDR, the performance is disastrous in the default configuration, with a massive loss of detail in the shadows.
- ✅ The monitor covers approximately 85% of the BT.2020 color space, which is a significant improvement over the previous generation.

3. 💡 Brightness and Contrast: Does It Fulfill the Promises of Greater Luminosity?
- ❌ The maximum brightness in HDR (10% window) is not significantly better than previous generation WOLED panels, and may even be lower than some older MLA WOLED panels.
- ✅ The monitor handles ambient light well, offering good perceived contrast in bright environments thanks to its low black levels (0.04 nits).
- ⚠️ It is speculated that the brightness could be artificially limited for fear of burn-in.

4. 🕹️ Gaming Performance: A Strong Point Despite the Deficiencies
- ✅ The monitor offers a very fluid and responsive gaming experience thanks to its near-instantaneous pixel response time and low input latency (24ms).
- ✅ Motion clarity is excellent, especially at 280 Hz, which makes it easier to track targets in fast-paced games.
- ✅ It uses a new RGWB subpixel arrangement that improves text clarity.

5. 🖼️ Clarity and Coating: The Monitor's Achilles Heel
- ❌ The grainy matte coating negatively affects the overall clarity of the image, giving it a blurry and oily appearance.
- ✅ The menu and firmware are acceptable, and the viewing angles are good, although with slight color variations.
- ❗ The reviewer gives it a rating of 3/10 and does not recommend the monitor in its current state, suggesting waiting for glossy versions from other manufacturers.
